Solution Overview

Problem

Existing pressure infusion devices for administering liquids to patients through IV bags lack a secure and transparent mounting system that allows for easy visualization of infusible liquid contents and efficient pressurization.

Innovation Solution

A pressure infusion device featuring a sealed bag of flexible, heat-sealable material with a layer of substantially transparent material, where the bag's edge portions are folded over and heat-sealed to the transparent layer through holes, enabling secure mounting and visualization of the infusible liquid, along with a U-shaped mounting member for pressurization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional mounting system is used for the IV bag, then the device structure is simple, but the visualization of infusible liquid contents and secure mounting is compromised

Engineering Contradiction:
Improvesecure mountingVSAvoidmounting system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the mounting function and visualization function into a single integrated transparent layer. The transparent layer serves dual purposes: it secures the IV bag through the hole structure while simultaneously allowing visualization of the liquid contents and barcodes, eliminating the need for separate mounting and viewing components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transparent layer is designed as a multi-functional component that performs multiple functions: mounting the IV bag securely through its hole structure, allowing visualization of liquid contents, and enabling barcode scanning. This universal component replaces what would traditionally require multiple separate parts.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Illumination intensity

If the bag material is made opaque for durability, then the bag structure is strong, but the visibility of contents and barcodes is lost

Engineering Contradiction:
Improvevisibility of contentsVSAvoidbag material durability
Core Design Contradiction:
Illumination intensityVSStrength

Solution Approach 1:

The patent applies different material properties to different parts of the system. The bag itself uses flexible heat-sealable material for durability and containment, while the mounting layer uses transparent material for visualization. Each material is optimized for its specific function without compromising the other.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses a composite structure combining flexible heat-sealable bag material with a transparent mounting layer. This composite approach allows the bag to maintain its structural integrity while the transparent layer provides visualization capabilities, achieving both strength and transparency requirements.

Inventive Principle:
Principle #40Composite materials

3Reliability

If the edge portions are sealed without holes, then the seal is complete and secure, but the mounting and attachment functionality is lost

Engineering Contradiction:
Improveseal integrityVSAvoidmounting functionality
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The transparent layer is segmented with multiple holes positioned at specific locations. These segmented openings provide mounting and attachment functionality while the surrounding material maintains seal integrity. The segmentation allows functional holes without compromising the overall sealing capability of the edges.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holes in the transparent layer act as intermediary elements that facilitate mounting functionality. They provide the necessary openings for attachment while the transparent material itself serves as the mediating structure that maintains both seal integrity and mounting capability simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)
